[0001] The utility model relates to the technical field of couplings, in particular to a connecting accessory of a coupling. Background Art

[0002] The existing coupling refers to a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances.

[0003] At present, an existing insulating flange coupling (such as patent number: CN218844894U) discloses an insulating flange coupling, including two groups of half couplings, each of which is provided with a mounting ring plate; the two groups of mounting ring plates are provided with a rubber shell, an insulating plate is provided in the rubber shell, the insulating plate is arranged between the two groups of mounting ring plates, and the two groups of mounting ring plates are provided with multiple groups of fixing bolts, the fixing bolts are threaded with fixing nuts, and the fixing bolt heads and fixing nuts are in contact with the rubber shell; the beneficial effect of the utility model is that the rubber shell and the insulating plate arranged as above can prevent the two groups of half couplings from contacting each other, thereby blocking the current, and at the same time, because the rubber shell wraps the mounting ring plates on the two groups of half couplings, thereby wrapping the insulating plate, it can prevent energized impurities from adhering to the insulating plate and affecting the insulation effect.

[0004] However, in the process of implementing the above technical solution, it was found that there were at least the following problems: the connecting accessories of the above coupling are fixing bolts and fixing nuts, and the connection position between the fixing bolts and the fixing nuts is exposed to the outside world. Foreign impurities adhere to the connection position and fill the gaps between the threads, which makes it difficult to disassemble the fixing bolts and the fixing nuts. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a connection accessory for a coupling, which solves the technical problem that foreign impurities adhere to the connection position and fill the gaps between the threads, making it difficult to disassemble the fixing bolts and nuts.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A connection accessory of a coupling comprises a coupling body, the outside of which is movably connected with six bolts, the outside of each bolt being threadedly connected with a nut, a protection mechanism being provided at one end of each bolt close to the nut, each protection mechanism comprising a protective tube, an internal thread, a limit ring and a limit plate, the protective tube being provided on the outside of the bolt, the internal thread being provided on the inner side of the protective tube, the protective tube being threadedly connected to the outside of the bolt via the internal thread, the limit ring being fixedly mounted on the outside of the protective tube, the limit plate being provided on the outside of the protective tube, the outside of the coupling body being slidably connected with a connecting plate, the outside of the connecting plate being provided with openings, the number of the openings being six, the connecting plate being slidably connected to the outside of the protective tube via the openings, and the connecting plate being located between the limit ring and the limit plate.

[0013] (III) Beneficial effects

[0014] 1. By setting a protective tube and matching the internal thread, when the nut is threadedly connected to the outside of the bolt, the connecting plate is slidably connected to the coupling body. At this time, the protective tube is rotated so that the protective tube is threadedly connected to the outside of the bolt through the internal thread until the protective tube covers the nut to prevent foreign impurities from adhering to the connection position and filling the gap between the threads, making it more difficult to disassemble the fixing bolts and nuts.

[0015] 2. By setting a limit plate and cooperating with the spring, the limit plate is pushed to make it enter the interior of the slide groove. At this time, the limit plate cannot limit the protective tube. At this time, the protective tube slides downward and the connection with the opening is released. At this time, the protective tube is removed. At this time, a new protective tube is slid and connected to the inside of the opening, and the limit plate is pushed to make the limit plate enter the interior of the slide groove. At this time, the spring is compressed. At this time, the protective tube continues to be pushed until the limit plate is located on the other side of the connecting plate. At this time, it slides to the outside of the slide groove under the action of the spring. At this time, the protective tube is installed. When any protective tube on the connecting plate is damaged, you only need to remove the damaged protective tube without replacing the entire protective mechanism, which reduces material waste and saves resources.

[0022] The embodiment of the present application provides a connection auxiliary part of a coupling, which effectively solves the technical problem that foreign impurities adhere to the connection position and fill the gaps between the threads, making it difficult to disassemble the fixing bolt 2 and the fixing nut 3.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution in the embodiment of the present application effectively solves the technical problem that foreign impurities adhere to the connection position and fill the gaps between the threads, which makes it difficult to disassemble the fixing bolt 2 and the fixing nut 3. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a connection auxiliary part of a coupling, which includes a coupling body 1, six bolts 2 are movably connected to the outside of the coupling body 1, and a nut 3 is threadedly connected to the outside of each bolt 2. A protective mechanism is provided at one end of each bolt 2 close to the nut 3, and each protective mechanism includes a protective tube 4, an internal thread 5, a limiting ring 6 and a limiting plate 7. The protective tube 4 is arranged on the outside of the bolt 2, and the internal thread 5 is opened on the inner side of the protective tube 4. The protective tube 4 is threadedly connected to the outside of the bolt 2 through the internal thread 5, the limiting ring 6 is fixedly installed on the outside of the protective tube 4, and the limiting plate 7 is arranged on the outside of the protective tube 4. The sliding connection has a connecting plate 8, and an opening 9 is opened on the outside of the connecting plate 8. There are six openings 9. The connecting plate 8 is slidingly connected to the outside of the protective tube 4 through the opening 9. The connecting plate 8 is located between the limit ring 6 and the limit plate 7. By setting the protective tube 4 and cooperating with the internal thread 5, when the nut 3 is threadedly connected to the outside of the bolt 2, the connecting plate 8 is slidingly connected to the coupling body 1. At this time, the protective tube 4 is rotated so that the protective tube 4 is threadedly connected to the outside of the bolt 2 through the internal thread 5 until the protective tube 4 covers the nut 3 to prevent foreign impurities from adhering to the connection position and filling the gap between the threads, making it more difficult to disassemble the fixing bolt 2 and the fixing nut 3. At the same time, it also provides protection for the bolt 2 and the nut 3 to reduce the probability of damage to both.

[0026] A rotating plate 10 is provided on the outside of each protective tube 4. A groove 11 is opened on the outside of each protective tube 4. The rotating plate 10 is arranged inside the groove 11 to facilitate the rotation of the protective tube 4. A movable groove 12 is opened inside each groove 11. A movable plate 13 is slidably connected inside each movable groove 12. The rotating plate 10 is fixedly installed on the outside of the movable plate 13 to increase the length of the rotating plate 10 so that the user can hold the rotating plate 10 more easily.

[0027] Each protective tube 4 is provided with a slide groove 14 on the outside, and the limit plate 7 is slidably connected to the inside of the slide groove 14 to facilitate the disassembly and assembly of the protective tube 4. Two built-in grooves 15 are provided inside each slide groove 14, and a built-in plate 16 is slidably connected to the inside of each built-in groove 15. The two built-in plates 16 are fixedly installed at both ends of the limit plate 7 to avoid the release of the connection between the limit plate 7 and the slide groove 14. A spring 17 is fixedly connected to the inside of each slide groove 14, and the limit plate 7 is fixedly connected to the outside of the spring 17 to provide support for the limit plate 7. By setting the limit plate 7 and cooperating with the spring 17, the limit plate 7 is pushed to enter the inside of the slide groove 14. At this time, the limit plate 7 cannot limit the protective tube 4. At this time, the protective tube 4 slides downward and the connection with the opening 9 is released. At this time, the protective tube 4 is disassembled, and the new protective tube 4 is slid and connected to the inside of the opening 9, and the limit plate 7 is pushed to make the limit plate 7 enter the inside of the slide groove 14. At this time, the spring 17 is compressed. At this time, the protective tube 4 continues to be pushed until the limit plate 7 is located on the other side of the connecting plate 8. At this time, it slides to the outside of the slide groove 14 under the action of the spring 17. At this time, the protective tube 4 is installed. When any protective tube 4 on the connecting plate 8 is damaged, it only needs to be disassembled, and there is no need to replace the entire protective mechanism, which reduces material waste and saves resources.

[0028] Working principle:

[0029] In the first step, by setting the limit plate 7 and cooperating with the spring 17, the six protective tubes 4 are respectively slidably connected into the inside of the six openings 9, and the limit plate 7 is pushed to make the limit plate 7 enter the inside of the slide groove 14. At this time, the spring 17 is compressed, and the protective tube 4 is continued to be pushed until the limit plate 7 is located on the other side of the connecting plate 8. At this time, it slides to the outside of the slide groove 14 under the action of the spring 17. At this time, the six protective tubes 4 are installed on the connecting plate 8;

[0030] The second step is to set a protective tube 4 in conjunction with the internal thread 5. When the nut 3 is threadedly connected to the outside of the bolt 2, the connecting plate 8 is slidably connected to the coupling body 1. At this time, the protective tube 4 is rotated so that the protective tube 4 is threadedly connected to the outside of the bolt 2 through the internal thread 5 until the protective tube 4 covers the nut 3 to prevent foreign matter from adhering to the connection position and filling the gap between the threads, making it more difficult to disassemble the fixing bolt 2 and the fixing nut 3. At the same time, it also provides protection for the bolt 2 and the nut 3 to reduce the probability of damage to both.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
